Solar panels can definitely act as insulation! In fact, a study conducted by researchers at UC San Diego Jacobs School of Engineering found that solar panels can reduce the amount of heat reaching the roof by an incredible 38%. Most people think solar panels alone determine how much energy you get, but the way your home holds onto that energy matters just as much. Insulation helps keep the heat in during winter and out during summer, making your solar system work smarter, not harder. This underscores the importance of insulation in maintaining indoor temperatures. Solar panels work by converting sunlight into electricity, which can then be used to run appliances and lights in your home.
